Eshabhu yeJinbin, kwenziwa ngokwezifiso ezintathuama-valve e-gogglengoba amakhasimende asezoqedwa. Abasebenzi benza umsebenzi wokugcina kubo. Laba abalandelii-valve eyimpumputhe emisesenosayizi we-DN1450, ifakwe idivayisi kagesi. Baye babhekana nokuhlolwa kwengcindezi okunzima nokuhlolwa kokuvula nokuvala futhi balinde ukupakishwa nokuthunyelwa.

Ivalvu yepuleti eyimpumputhe yomkhakha omkhulu enobubanzi obungu-DN1000 nangaphezulu ayimishini ebalulekile eklanyelwe ukuhlangabezana nezidingo zokuhlukaniswa kwezinhlelo zamapayipi anobubanzi obukhulu kakhulu.

Mayelana nezinzuzo, eyokuqala ukusebenza kwayo okuvelele kokubeka uphawu. Lolu hlobo lwe-valve lusebenzisa kakhulu ukwakheka kokuvala kabili kwe-"elastic seal + metal hard seal", esakwazi ukuzuza ukuvuza okungu-zero ngisho nangaphansi kwamadayamitha amakhulu we-DN1000 nangaphezulu. Ifaneleka ngokukhethekile ezimweni ezinezidingo eziqinile zokuvala ezifana negesi kanye nemidiya enobuthi, ukugwema inkinga yamandla angalingani endaweni yokuvala okubangelwa ububanzi obukhulu.

Okwesibili, isebenza kahle kakhulu futhi ilungele ukusebenza. Isakhiwo esimise okwefeni sihlangene kakhulu kunepuleti eliyimpumputhe lendabuko, futhi isisindo salo singama-60% kuphela aleso sevalvu yesango enobubanzi obufanayo. Ingahlanganiswa namadivayisi kagesi kanye ne-pneumatic drive ukuze kuzuzwe ukuvulwa nokuvala okukude, ukuxazulula inkinga yokusebenza kanzima kwezandla kwama-valve anobubanzi obukhulu. Isikhathi sokuvula nokuvala se-valve eyodwa ngokuvamile silawulwa phakathi kwemizuzwana engu-30, kuthuthukisa kakhulu ukusebenza kahle kokusebenza.

Ngaphezu kwalokho, ine-redundancy eqinile yokuphepha, ifakwe imishini yokukhiya imishini kanye nokushintshashintsha ukuvimbela ukungasebenzi kahle. Umzimba we-valve oyimpumputhe wenziwe ngensimbi enamandla amakhulu noma amapuleti ensimbi ashiselwe, angakwazi ukumelana nokucindezela okuphezulu (imvamisa kufika ku-1.6MPa) kanye nomthelela, futhi ifanele izimo zokusebenza eziyinkimbinkimbi. Ngaphezu kwalokho, izindleko zokunakekela ziphansi. Izingxenye zokuvala zingahlakazwa futhi zishintshwe ngokuhlukana ngaphandle kwesidingo sokuqaqa lonke ipayipi. Ifaneleka ngokukhethekile izimo zokukhiqiza eziqhubekayo ezinhlelweni zamapayipi ezinobubanzi obukhulu lapho “ukuvala shaqa kusho ukulahlekelwa”.

Izimo zohlelo lokusebenza zigxile kakhulu ezindaweni ezibalulekile ezidinga ukuhlukaniswa kobubanzi obukhulu: Ebunjiniyela begesi kamasipala, ivame ukusetshenziswa emigqeni emikhulu yamanethiwekhi egesi yemvelo yasemadolobheni anobubanzi obusuka ku-DN1200 kuya ku-DN2000, ukuze kuzuzwe ukwahlukaniswa kokuphepha ngesikhathi sokulungiswa kwamapayipi nokuxhumeka kwegatsha, ukugwema ukuphuma kwegesi enkulu. Emayunithi okukhipha amanzi emkhathini nase-vacuum kanye namayunithi aqhekekayo embonini ye-petrochemical, amapayipi amakhulu okuthutha uwoyela ongahluziwe nemikhiqizo kawoyela ocolisisiwe enobubanzi obungaphezu kwe-DN1000 adinga ukushintsha njalo izinqubo noma ukuhlukanisa amathuluzi.

Izici zabo zokuvula nokuvala ngokushesha zinganciphisa isikhathi sokuphazamiseka kokukhiqiza. Ezinhlelweni ezimanzi ze-desulfurization/denitrification zemboni yamandla, ilungele amapayipi egesi e-flue ayinhloko anobubanzi obuyi-DN1500 noma ngaphezulu, futhi ingahlukanisa igesi eshisayo eshisa kakhulu (enokumelana nezinga lokushisa okungafika ku-300℃) ngesikhathi sokulungiswa kwe-reactor. Uhlelo lokususa uthuli olomile lwegesi yesithando somlilo embonini yensimbi ludinga ukuthi amapayipi adlulisa igesi anobubanzi be-DN1200 nangaphezulu amelane nokuguguleka kwemithombo yezindaba equkethe uthuli. Isakhiwo sayo sensimbi sokuvala kanzima singasebenza ngokuzinza isikhathi eside.

Njengomkhiqizi oneminyaka engu-20 wamavalvu ensimbi (i-Electric Blind Valve), i-Jinbin Valves inikeza amakhasimende izixazululo zokulawula uketshezi ezisezingeni eliphezulu kanye nesevisi yomuntu ngamunye. Uma unanoma yimiphi imibuzo ehlobene, sicela usithinte ngezansi futhi uzothola impendulo kungakapheli amahora angama-24!
